GAS TURBINE UNIT Russian patent published in 2018 - IPC F02K3/04 F02K3/08 

FIELD: turbines or turbomachines.

SUBSTANCE: gas turbine unit consists of input device, fan, internal circuit, external circuit. Inside the internal circuit the compressor with the air take-off for the fan and the compressor drive turbine cooling, the combustion chamber, the fan and the compressor drive turbine, and the internal circuit output device are located. Inside the external circuit the heat exchanger, in which air from the mixer is circulated, in which the air coming from the compressor and the air coming from the heat exchanger are mixed, and the external circuit output device are located. Inside the internal and external circuits behind the fan and the compressor drive turbine the heat exchanger-regenerator is located. Internal circuit output device is made in the form of the exhaust branch pipe. External circuit output device is made in the form of the free turbine.

EFFECT: invention allows to raise the gas in front of the turbine temperature and to lower the outgoing gases temperature, which leads to increase in the heat engine cycle operation and efficiency.
